Garage



Patented Dec. 1, 1931 PATENT OFFICE JAN VOJACEK. OF PRAGUE,CZEOIHDSLOVLKIL GARAGE Application filed June 12, 1928, Serial No.284,781, and in Czechoslovakia February 11, 1928.

This invention refers to parking arrangements, garages or storagebuildin for storing motor vehicles, the principal o ject being toprovide the maximum storage space while permitting the vehicles whencoming out of their stalls, to continue in the same direction of travelin which they entered the stalls, so that there is no backing ofvehicles,

The single figure of the accompanying 1o drawing shows a plan view ofthe garage according to the present invention.

The garage comprises a continuous helical belt of dia onally arrangedstalls disposed therein, an three helical gangways.

The stalls are arranged in a continuous spiral beltand communicate onboth ends directly with the low spiral ways 32 and 33.

The third spiral way 34 is placed preferably inside the inner spiral 33,it can however surround the outer spiral 32 instead, and has an inversetwist in relation to the spirals 32 and 33. The spirals 34 and 33 areinterconnected by openings 35 which are placed wherever these twospirals intersect one in the same horizontal plane. In order tofacilitate the passage of cars from one spiral to the other, sectors 34,and if desired also sectors 33 and 32', corresponding in altitude and incircumference to the openings 35, are horizontal. The third spiral 34may, but need not neces- 1 sarily, have the same number of threads andthe same pitch as spirals 32 and 33. In the former case the openings 35are placed all in one vertical column but the gradients of the spiralsdiffer considerably, whilst in the latter case the adients of the spiral34 can be chosen equa to, or even easier than, the

gradient of the adjacent spiral 33.

The spirals 32, 33 and 34 need not be circular, but can have inground-plan any suitable outline which secures thebest utilization ofthe given building-lot. Especially the outer spiral way 32 can have alykgonal outline, preferably with round 0 corners, adapted to theoutlines of the building lot: if the inner spirals 33 and 34 arecircular or elliptical, this arrangement gives the advantage of stalls31 of unequal len h, which are thus suitable for parking vehic es ofdifierent lengthand size, without any space wasted.-

The spaces 36, 37 can be used for stairs, lifts, cloak-rooms, stores,oflices, repair-workshops, etc.

It is evident that the spiral 34 can be used by ascendingland thespirals 33 and 32 by descending, ve 'cles, or vice versa, without anychange in the inner arrangements being needed. In the former case a carhalving the stall 31 will enter the building at 38, ascend by spiral 34up to the platform 34 which is next highest to 1ts stall, pass throughthe opening 35 onto the platform 33, descend without backing or changingthe direction of travel along t e spiral 34, and enter its stall 31'.The same car leaving the garage, will continue in the original directionof movement from its stall 31' on to and along, the spiral 32, and leavethe building at 39. In the latter case this procedure will be reversed,the car entering the building at 39, ascending along the spiral 32 toits stall 31, than continuing along the spiral 33 to the next 0 ening35, passing through the latter on to an descending along, the spiral 34,and leaving thebuilding at 38.

Claim:

A plural-storied garage having a continuous helical belt of diagonallyarranged stalls disposed therein, a helical entrance gangwaycommunicating with the entrance ends of the stalls, a helical gangwayinclined in the same direction as the entrance gangway and communicatingwith the exit ends of the stalls, a third helical gangway inclined inthe opposite direction to the two above named gangways and disposedadjacent to one of the two above named gangways, the last named thirdgangway communicating with that of the rst named two gangways to whichit is adjacent, at places at which these two gangways adjacent to eachother intersect one and the same horizontal plane.

In testimony whereof I aflix my signature.

JAN VOJACEK.
